ABSTRACT:
A vehicle wheel end assembly (10) is adaptable for use with an on-board central tire inflation system. The assembly provides a passage for the routing of air between a central source and the vehicle tire (25). The assembly comprises a stationary spindle (12) and a rotational hub (14) mounted thereon. A collar (34) is mounted on the inboard end of the spindle in interfacing relation with an inboard extension (50) of the hub. An air chamber, defined by the radial spacing of the collar (34) and hub extension (50), communicates air passages in the collar and hub (36, 44). The chamber is fitted with a pair of rotary seals (72, 74) to seal the air passage between the stationary collar (34) and rotating hub (14). The rotary seals (72, 74) each include an integral sealing lip (80) which responds to pressurization of the chamber by biasing into sealed relation with the outer surface of the collar (34).
